Is it possible...

[BLAZE]

Does anybody know if you can control the speed of your pnuematics system from a remote control? Any suggestions would be greatly appreciated. Thank You!

If by speed of pneumatics you mean by speed how fast the pistons move I don't think its possible to control with the solenoids we get in the kit.

for our purposes, i dont think so. They make them for ricer cars wit the air bag suspension, im not entirely sure how they work as far a wiring goes.

Second thought, can you wire a servo, and then attach it to the valves on the actuator? In theory, it would work if you had a large gear on the servo and a small on the valve knob, similar to the chain and sprocket for the camera mounts.


just my $.02

Yeah, my "ricer car" has them. It's called a bleeder valve. You can get them from any major pnumatics components distributor.

In the kit there are little "flow rate control fittings" they are the ones with the little white knobs on top. You can't actuate it remotelty, but maybe if you wanted to get fancy with a servo you could.

definitly. and not just ricers have them. ricers. heh. never know if you're making fun of us or not lol. well anyways. back to the topic. uhh dont maybachs have it too? and juuust a couple other goodies in it?

I asked a guy at SMCUSA in Boston, a company that makes pneumatics systems, and he told me something about hooking up a acceleration/deceleration circuit. I'm not the "technical guy" on our team, so I was wondering if any of you guys know what he was talking about, and is it legal to use on the robots this year. By the way, you're the only people who have answered any of my questions. I've been on every forum and haven't got a single reply! Thanks for replying... I was beginnning to wonder if anyone actually replyed here... no pun intended. Thanks for your help.

yes, i understand what he was saying, basically it controls the amount of air that is let in and out. We tried it last year and it ended up being aborted because it was soo complex. It is possible, however those circuits tend to be cranky and i wouldn't advise doing it.

sorry, its a jeep thing. Being a jeeper, we tend to call the lowered faster cars, ricers, due to them bing imports. Its a diragatory(sp) slang term, but it seems to have become part of the world.

I know more about suspension lifts and controll arms than i do high output engines and airbags

You could have 2 speeds by running the vents to a solenoid valve, and use it to switch between two flow controls.

[BLAZE]

Yeah, someone was telling me that just today. We posted a question about it on the FIRST Q&A site, but it wasn't specific enough... my buddies want to know if anyone knows how to wire a solenoid valve? It figures it'd be complex... tooo much for brain!!!!! AHHHH!!! NEWay, thanks for the advice, it helps a lot. Do you know anybody going to the Arizona Regional? That's where my team will be heading... Never been off the east coast and it'd be nice to meet some "Westerners", pardon the expression... no offense.
Thanks again!

know im coming into this discussion late, but there ARE things you can do programming wize to change the speed at which it comes out and also how far it comes out.

1. changing how fast it comes out:
-tell the programmer to set the code so that when the soleniod is fired, make it relay on and off--the simplest solution to changing speed by controlling the amount of time that the solenoid allows air flow.

2. changing how far it comes out:
-hook up a second solenoid to the exhaust of the first one. in order for this to work, use something like a joystick interface, where you have control over positive, neutral, and negative current on the fly. dont have the exact code off the top of my head, but we did it this year and worked like a charm.

to control them remotely? hm. if you could change the frequency of open/close valve on the first solenoid by a dial and then the firing by a joystick, it could all be incorporated on a remote control of some sort.

just stopping in and giving my 2 cents, even though theyre late.
